Symptoms

  • Unity Connectivity Services failed.
  • Connectivity Services unreachable.
  • Connectivity Services failed during a health check.
  • Error code: 0x6000cbb
  • Error code: 0x6400c1f

Cause

This issue has been identified after upgrades to both UnityOS 5.5.2 and 5.5.3.

 

The established root cause pattern for /hostmnt being full is as follows:

  1. During or related to an upgrade, a SQLite database upgrade fails.
  2. The ESE container's /dev/loop0 file system fills up (100% at /opt/ese/var).
  3. The database upgrade gets stuck applying "sql upgrade 52".
  4. The ESE container cannot start due to no disk space.
  5. SupportAssist configuration fails with error 0x6400c1f.

Resolution

 

  1. Determine if you are receiving Error code 0x6000cbb or Error code 0x6400c1f by checking the 'Alerts' tab in Unisphere or by running a health check:
